Creating GEO-enabled applications with MySQL 5.6

In my previous post I’ve showed some new MySQL 5.6 features which can be very helpful when creating geo-enabled applications. In this post I will show how we can obtain open-source GIS data, convert it to MySQL and use it in our GEO-enabled applications. I will also present at the upcoming Percona Live conference on this […]

DBA 101: Sometimes forgotten functionality in the MySQL client

The MySQL client has some functionalities some of us never use. Why would you use them and what is the added value of this? Every DBA and developer has had a moment when he or she needs to connect to a MySQL database using the command line tool. Therefore I’ve written down an explanation of […]

Past, present and future of MySQL and variants: linux.conf.au 2014 video

Early this month I spoke at linux.conf.au in Perth, Australia, where I presented “Past, Present and Future of MySQL and variants.” Here’s my presentation in its entirety. Please let me know if you have any questions or comments. (linux.conf.au is widely regarded by delegates as one of the best community run Linux conferences worldwide.)

Linux performance tuning tips for MySQL

Because most MySQL production systems probably run on Linux, I’ve decided to place the most important Linux tuning tips that will help improve MySQL performance. There is nothing new here, most of them are well known, however, I’ve decided to collect those Linux configuration tips into 1 blog post. Filesystem ext4 (or xfs), mount with […]

MySQL encryption performance, revisited

This is part two on a two-part series on the performance implications of in-flight data encryption with MySQL. In the first part, I focused specifically on the impact of using MySQL’s built-in SSL support with some rather surprising results. Certainly it was expected that query throughput would be lower with SSL than without, but I […]

MySQL on Windows: A survival guide for Linux-based DBAs

Next week, on Nov. 6, I will be delivering a webinar about running MySQL on Windows, with a strong focus on Linux-based sysadmins and DBAs – and how not to go crazy in the process. An interesting (and challenging!) part of working for Percona is that you never know what kind of setup a customer […]

InnoDB performance optimization basics (redux)
